This Catalyst article looks at 3D printing, a new technology which is rapidly finding applications. Although probably too slow for mass production it is useful for producing prototypes and tailor-made items. In a 3D printer, layers of polymer beads are printed one on top of the other. Heat melts the polymer beads...

Produced by the Learning and Skills Improvement Service (LSIS), these resources are aimed at mathematics practitioners. .

Sessions in this resource look at:

• Probability scales (using higher order questions)
• Probability, fractions, decimals and percentages (creating connections between...

A Catalyst article about the human gut and the many microbes it hosts, mainly bacteria. Probiotics are live bacterial ingredients or supplements designed to multiply in the colon and have an impact on health. A prebiotic is a carbohydrate that is not digestible by humans. The article examines the role they play,...

A Catalyst article describing how process chemists work in the pharmaceutical industry, devising methods of making new drugs.
